15KV ALUMINUM CONDUCTOR XLPE INSULATED STEEL WIRE ARMORED CABLE

Specifications

15KV ALUMINUM CONDUCTOR XLPE INSULATED STEEL WIRE ARMORED CABLE

8.7/15kV AL/XLPE/SWA/PVC(or PE) Power Cable

1. Description  15KV ALUMINUM CABLE   15KV ALUMINUM CABLE   15KV ALUMINUM Construction: Compacted stranded circular aluminum conductor, extruded semi-conducting compound as conductor shield, cross-linked polyethylene (XLPE) insulation, semi-conducting compound as insulation shield, copper tape or combination of copper wire and tape as metallic screen, three cores assembled together with non-hygroscopic polypropylene filler, wrapped with binder tape, PVC inner covering as armoring bedding, galvanized steel wire armored, PVC or PE outer sheath.

2. Operating Characteristics
Rated voltage U₀/U(U_m): 8.7/15(17.5)kV
U₀ is the rated power frequency voltage between conductor and earth or metallic screen for which the cable is designed;
U is the rated power frequency voltage between conductors for which the cable is designed;
U_m is the maximum value of the “highest system voltage” for which the equipment may be used.
Max. permissible continuous operating temperature of conductor: 90 °C
Max. temperature of conductor during short-circuit (5s max. duration) shall not exceed: 250 °C
The ambient temperature under installation should not be lower than: 0 °C
The bending radius of cable is recommended as following:
For single core cable: not less than 15 times of the diameter of cable
For three core cable: not less than 12 times of the diameter of cable
When the armored single core cable used for Alternative Current(AC) system, the armoring material should be non-magnetic.

3. Application
The cable is used for fixed installations such as electric power distribution networks or industrial installations, which is laid indoors, outdoors, in tunnel, in cable trench, or direct in ground, able to bear external mechanical force and certain pulling force.
